SAW GUARD.

Substitute for application Serial No. 740,887, filed Gctooer 1, 1924. This application filed February 23,

1826. Serial No. 90,227.

My invention relates to guards for cutoff saws.

The object of my invention is to provide a guard adapted for a movable saw that will protect the operator in all positions of adjustment of the saw and in the travel of the same through the work and also that will be readily movable to permit access to the saw and the removal of the latter when it is desired to change the same.

lVith these objects in view, my invention is embodied in preferable form in the de vice hereinafter described and illustrated in the accompanying drawings in which Figure 1 is a side view in elevation of a cut-off saw with my invention applied thereto.

Figure 2 is a similar view with the saw advanced and in position after it has passed through a board;

Figure 3 is an end view in elevation;

Figure 4 is a side view in elevation of the base, guide, cover and retaining bar or cap for the cover, showing the retaining bar unlatched and in raised position to release the cover;

Figure 5 is a top plan view of the retaining bar or cap for the cover showing its latch;

Figure 6 is a detail top plan of the retaining bar with spring latch removed;

Figure 7 is a detail end view of the cover;

Figure 8 is a detail top plan view of the cover;

Figure 9 is a detail end view of the base and guide at the latch end of the device;

Figure 10 is a detail end view of the re t aining bar viewed from its hinged end; and

Figure 11 is a detail side elevation of the retaining bar.

Referring to the drawings, 1 indicates a swinging arm in which a rotary cut off saw 2 is carried. This arm is adapted to be moved back and forth in the plane of the saw 2 by a foot pedal, or other suitable means, operated by the sawyer toward and from a suitable work table or bed 3, adapt-- ed to support the board l to be sawed. Bolted to this saw carrying arm is an up rightbracket 5, to the upper end of which is fixed a pivot bolt 6, on which is journaled one end of an arm 7. The arm 7 is detachably held on the pivot bolt by means of a washer, and a cotter pin 8.

The other end of the arm 7 is pivoted at 9 to a depending extension 10, of a sli'dable saw cover member 11, which is formed with an upper curved slotted part adapted to fit over and enclose the upper part of the saw so as to provide a guard therefor to protect the operator. The forward end of this cover is provided with a flat, horizontal lip 12, adapted to take over the board or other work to be sawed, so as to thereby extend the protection of the guard over the point of contact of the saw with the board, while at the same time not interfering with the operation of the saw.

The cover member is provided with a longitudinal and horizontal flange 13, having atits extremity upper and lower vertical guide lips 14 and 15, the flange. bearing upon and being adapted to slide on a flat guide and support arm 16 projecting at right angles from the vertical web of a fixed base member 17, while the lower lip of the cover flange takes over the edge of this supporting arm and guides the cover in 1011- gitudinal movement and prevents displacement thereof. The base 17 is fixed to a bed plate 18 carried by any suitable support, the forward end of this plate being integral with the board support table.

Pivoted at one end at 19 to the web of the base is a retaining and guiding bar 20 adapted to lie over the flange 18 of the cover and retain the latter in place on the guide surface of the base while at the same time permittingthe longitudinal sliding movement of the cover. slotted side'ext'ension, one wall of which takes over the web of the base 17, while the inner and shorter wall thereof takes over the upper lip 1a of the cover to guide the latter. The bar is further provided with aligning and retaining means comprising an open bifurcated end 21 embracing a hook 22 rising from the base. To hold the retaining bar 20 in locked position down against the cover, it is provided on its upper surface with a latch 23 adapted to be releasably spring pressed into engagement with the hook 22.

In the operation of the device, the saw advanced to the work by moving its arm 1 This bar 20 has a vertically by a foot pedal or similar means and then carried through the work in a continued movement of the said arm. As this support advances, it carries with it the arm 7, which in turn slides'forward the slotted cover 11, maintaining the latter over the saw throughout the entire movement of the latter and thus providing an effective guard for. the operator during the sawing operation. a I

lVhen it is desired to remove the cover for the purpose of replacing the saw, the spring latch 23 of the retaining bar is releasedfrom the hook 22 and the bar 20 is swung upward on its pivot. The cover may then be lifted sothat its lower lip 15 will be clear of the base, and, after the cotter pin 8 of the arm 7 has been removed, the

cover with the arm 7 connected thereto,may

be removed laterally so as to be free of the saw and permit the latter to be removed.

Having thus described my invention, what I claim is:

1. The combination with an arcuately movable saw extending through a slot in a saw table, of a saw guard, said saw guard arching the upper Side of the saw above the table, a bracket carried by the table, said guard being slidably connected to the bracket and in a channel thereof a pivoted member pivoted to thebracket adjacent one. end thereof, said pivoted member forming one side of the channel and latching means for said pivoted member.

2. The combination with an arcuately movable saw extending through a saw slot of a table, a pivoted arm supporting said saw, of a saw guard movable with said saw, said guard being slidably connected to a bracket carried by the table, a bracket carried by the pivoted arm below the table, a link between said last named bracket and the guard and forming means whereby upon movement of the saw and pivoted arm said guard will move therewith, said bracket carried by the table having a guideslot therein, a member carried by the guard and slid-ably mounted in the guide slot, a member pivoted to the bracket at one of its ends and forming the upper side of the guide slot, said last named member having latching connections at its free end with the bracket carried by the table.

3. The combination with a saw guard slidably mounted in a bracket carried by the upper side of a saw table and movable with a saw towards and away from a piece of work, of'supporting means for said guard, said means comprising a bracket carried by the table and having a guide slot therein, said guide slot being formed from hingedly connected members, latching means between said members and a member carried by the guard andslidably mounted in the guard slot.

I. The combination with a saw guard housing the upper side of a saw and arcu ately moving with the saw of a mounting for said guard, said mounting comprising a bracket disposed to one side of the saw, a member carriedby said guard and slidably mounted on the upper side of the bracket, a member pivoted to one end of the bracket and engaging the upper side of the member carried by the guard, thereby forminga guard slot for the guard member and latching means connecting the free end of the pivoted member to one end of the bracket. v

5. In combination with a saw support movable towards the work, a saw guard having a curved, slotted part adapted to embrace a saw and slidable radially of the saw, pivoted connections between the guard and support, a fixed base on which said guard slides and a releasable retaining and guide member for said guard.

6. In combination with a saw support, a sliding saw guard movable with said support, a fixed base member and a retaining bar between which said guard is held for longitudinal movement and flanged means on said parts to prevent lateral displacement of said guard- 7. In combination with a slidable saw guard, a retaining bar bearing on the same, said parts having flanges at right angles thereto to prevent lateral displacement and said retaining bar being hingedly mounted to permit the guard to be released and removed.

8. In combination, with a slidable saw guard, a hinged retaining and guiding member therefor, and a latch for said member. I

In testimon* whereof I aiiix my si nature.
